(sorry about nicking the picture from another forum, when I buy fish'n'chips they are wrapped in either plan white paper, or newspaper...)

I think the best solution depends on a clear objective. In the end, it comes down to physically fitting a new CPU card into a case (be that a PC type case or a QL case) and cost. So if new fast/wide bus expansion cards are likely to be produced, it is logical to design a new expansion system with ne...

The problem is that the QL produces a non-standard video signal in monitor mode :( This is a timing problem. Not a processing problem. Messing with the RGB signals cannot change the timing of the information in these signals. Unless you capture and store the information (like the GBS8220 RGB->VGA co...

I've used RetroShack for numerous cables over the years. They provide top quality kit and their support is top notch too! I have a couple of their QL Scart cables, they work well, I loose approx 3 characters in Monitor mode, but I don't think I loose any in TV mode. I too have a SCART cable for my ...

I hope there's a threshold beneath which it isn't worth the bother to charge? For the UK, currently £15. Value Added Tax (VAT) - Import VAT is charged at the same rate that applies to similar goods sold in the UK and applies to commercial goods over £15 in value, and on gifts that are over £36 in v...

I am currently favoring the idea of smaller, pre-decoded expansion slots with a 16- or 32K addressable area, plus an SPI interface. If the slots are empty, then RAM can be enabled in the empty space. Whichever route is taken, the objective needs to be clear. What is the intended use of any expansio...

Regarding power pins... The existing expansion connector has VIN (+9V nominal)(three pins), VP12(+12V) and VM12(-12V) only. Switching regulators are much better than the common 7805. They normally would not need heat-sinks even if the VIN was a regulated +12V. However, if users are using a typical ...
